The Spanish Civil War, which seemed very rudimentary to the powers like Britain, France, and Germany, was actually the strongest military force that the two major factions in Spain could muster.
More importantly, such military strength was only demonstrated after receiving substantial military aid from the German-Italian alliance and Russia.
Without the support of external powers, the Spanish Civil War would have been even more poorly fought.
As time entered February of 1937, Germany had achieved certain successes on the battlefields of Northern Europe.
Hundreds of thousands of soldiers had invaded the Nordic Trio, and after an entire winter's campaign, they had already captured vast territories in Sweden and approached the capitals of Norway and Finland.
Though the Nordic countries appeared vast in area, each had a small population. Combined with their prolonged disengagement from war, their military strength was not formidable.
